Shelby say: Simplifying
2x + 9 = 13 + -2x
Reorder the terms:
9 + 2x = 13 + -2x
Solving
9 + 2x = 13 + -2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2x' to each side of the equation.
9 + 2x + 2x = 13 + -2x + 2x
Combine like terms: 2x + 2x = 4x
9 + 4x = 13 + -2x + 2x
Combine like terms: -2x + 2x = 0
9 + 4x = 13 + 0
9 + 4x = 13
Add '-9' to each side of the equation.
9 + -9 + 4x = 13 + -9
Combine like terms: 9 + -9 = 0
0 + 4x = 13 + -9
4x = 13 + -9
Combine like terms: 13 + -9 = 4
4x = 4
Divide each side by '4'.
x = 1
Simplifying
x = 1

posyaquep say: Solve for x:
2 x + 9 = 13 - 2 x
Add 2 x to both sides:
2 x + 2 x + 9 = (2 x - 2 x) + 13
2 x - 2 x = 0:
2 x + 2 x + 9 = 13
2 x + 2 x = 4 x:
4 x + 9 = 13
Subtract 9 from both sides:
4 x + (9 - 9) = 13 - 9
9 - 9 = 0:
4 x = 13 - 9
13 - 9 = 4:
4 x = 4
Divide both sides of 4 x = 4 by 4:
(4 x)/4 = 4/4
4/4 = 1:
x = 4/4
4/4 = 1:

peevee say: 2x + 9 = 13 - 2x
2x + 2x = 13 - 9
4x = 4
x = 1

MICHAEL K say: x = 1.
-
Krishnamurthy say: x = 1
-
Paul say: 2x+9=13-2x
gather like terms
2x + 2x = 13-9
combine like terms
4x = 4
divide both sides by 4
x = 1

Mathias say: 2x + 9 = 13 - 2x.
2x + 9 - 13 + 2x = 0.
4x - 4 = 0.
4x = 4.
x = 4/4 = 1.
Ans.: x = 1.
-
D.W. say: Add 2x to both sides of the equation.
Subtract 9 from both sides of the equation.
Divide both sides of the equation by 4.

Como say: 4x = 4
x = 1
-
alex say: 2x+2x=13-9
solve for x
-
JOS J say: x = 1
-
g say: X=1 because if you subtract 9 from 13 you get 4 then you have 2X=4-2X add 2X to 2X Then u will have 4X=4 divided both sides by 4 and X will = 1
